Locking Type Thermal Photocontrol, 120 V

Thermal type photo controls provide dusk to dawn lighting control and a delay action, which eliminates loads switching OFF due to car headlights and lightning. The thermal type controls feature a cadmium sulfide photocell and polypropylene case to seal out moisture. The design utilizes a dual temperature compensating bimetal and composite resistor for reliable long life operation over ambient temperature extremes.
